MILAN — Italian firefighters working through the night, sometimes digging by hand, freed a 7-month-old baby Tuesday and then his two older brothers from the rubble of their home that collapsed when a 4.0-magnitude quake struck the resort island of Ischia during the height of tourist season.

At least two people were killed in the quake that struck just before 9 p.m. Monday, while another 39 were injured and some 2,600 were left homeless. The victims were an elderly woman who struck by masonry that fell from a church, and a second woman who was inside a building that collapsed.

In the hard-hit down of Casamicciola, dozens of firefighters worked for 14 hours to dig the Marmolo brothers out of their home, where they were trapped alone after their father was rescued and their pregnant mother managed to free herself.

Cheers went up with each rescue, which firefighters confirmed with exclamation mark-punctuated tweets. The first was baby Pasquale, who was shown on a video wearing a white onesie and appearing alert as he was passed to safety, around 4 a.m.

It took another seven hours to free the middle brother, 8-year-old Matthias, who was pictured in his underwear and covered with cement dust before being quickly loaded onto a stretcher and into an ambulance, and two more hours to free the eldest boy, 11-year-old Ciro, who was credited with helping save Matthias.

The children's parents were waiting for Ciro at the hospital's emergency room, his mother sitting in a wheelchair next to his father, Alessandro, whose hands were bandaged from a fracture.

"It was a terrible night. I don't have words to explain it," the father told RAI state television while rescuers were working to free the older two boys. "The entire second floor of the house collapsed, and the firefighters pulled me out. They were great."

He said his wife was in the bathroom and managed to escape through the window, but the older boys were in the bedroom in the family home while the baby was in a playpen in the kitchen.

Hospital officials said all three were doing well, with the older two boys being treated for dehydration and the oldest for a fracture to his right foot. They were expected to be discharged from the hospital Wednesday.

It wasn't immediately clear where the family would be staying.

"For three children saved from the rubble, we have witnessed a true miracle. They are miraculously healthy," said Virginia Scarfato, director of the Rizzoli hospital in Ischia.

The head of the financial police on the island said it was Ciro who helped save Mattias, pushing him under the bed.

"The gesture surely saved them both," said Andrea Gentile. "Then with the handle of a broom he knocked against the rubble, making them heard by rescuers."

Firefighter spokesman Luca Cari said they maintained voice contact with the two boys to keep them calm during the complex rescue operation to create an opening through the collapsed ceiling. The boys had been given bottles of water and a flashlight.

The quake hit during the height of the tourist season, with the island's population of 64,000 ballooning by another 150,000 at the time the quake struck. Italian television showed many visitors taking refuge in parks and sleeping under blankets in the aftermath while authorities began organizing ferries to bring tourists back to the mainland early Tuesday.

Tourism officials said that the damage was localized in two towns, and said much of the island was business as usual Tuesday. According to Ermanno Mennella of the Federablberghi hoteliers association in Ischia, just 10 of the island's 310 hotels had been impacted by the quake and only three or four were closed by it.

Together with the nearby island of Capri, Ischia is a favorite island getaway for the European jet set, famed in particular for its thermal waters. Casamicciola was the epicenter of an 1883 earthquake that killed more than 2,000 people.

Images from the quake zone show many buildings collapsed into rubble, while others showed signs of structural damage with deep cracks in exterior walls. Cars were overturned.

The extent of the damage for a relatively light quake raised questions about the quality of construction on the island in the seismically active area off Naples and the active volcano Vesuvius, and the prevalence of illegally built structures.

Fabrizio Pistolesi, the head of Italy's national architecture advisory board, told SKY that many buildings on the island were built before seismic codes were adopted. He also cited the high incidence of illegal construction on Ischia and generally in the Campagna region that includes both the resort island and Naples.

"We know well that in Campagna, more than 200,000 homes were illegally constructed, we are talking about homes constructed in absolute scorn of seismic norms," he told Sky TG24.

Former Naples prosecutor Aldo De Chiara told Corriere della Sera that most of the recently constructed buildings on Ischia were built without necessary permits, and many with poor quality cement. "We warned about the risk of collapses also in the case of not particularly serious temblors," De Chiara said. "Unfortunately, what we had denounced, happened last night."

The head of Italy's Civil Protection Agency, Angelo Borrelli, told reporters that 2,000 people had been left homeless in Casamicciola and another 600 in the towns of Lacco Ameno and Ischia. He said authorities were checking the stability of hotels to see if they could be used as temporary housing.

The quake came just two days shy of the one-year anniversary of a powerful 6.2-magnitude earthquake that devastated several towns in central Italy. The quake on Aug. 24, 2016 killed more than 250 people in Amatrice and beyond and set off a months-long series of powerful aftershocks that emptied many towns and hamlets of their people.

This story has been corrected to show that much of the island was business as usual on Tuesday, not Saturday.
